Abstract (en)

The control and clutch system for a rotary dobby has two return units (9) within the drive shaft (1), to push the control unit (7) into the second freewheel setting. Return unit (9) is an arc section or segment, at the inner surface of the drive shaft (1), each with two ramps (17) to move the controls. The controls (7) move against each other in a carrier (4) as simple cylinders with pistons. The controls are operated simultaneously by a magnet valve (8), or by a coil which generates a magnetic field together with two permanent magnets each in blind drillings so that the opposing poles are against each other. An Independent claim is also included for a clutch mechanism with a clutch ring with two diametrically opposed sections. It is assembled on the drive shaft (1) so that the sections are aligned with the holes (10). Two coupling components are locked and unlocked simultaneously in one of the sections to engage and disengage the eccentric disk with the drive shaft (1). The coupling components are a pawl and an auxiliary pawl, which pivot on the eccentric disk, each with a spring to tense them against the clutch ring. A locking lever prevents pawl movement. Two levers swing on the connecting rod, to be brought into engagement with the eccentric disk, to prevent the disk rotating when the assembly is in the freewheel setting.

Abstract (de)

Die Anordnung enthält einen Träger (4), der in einer als Hohlwelle mit in einer Radialebene angeordneten Löchern (10) ausgebildeten Antriebswelle (1) montiert ist, zwei Schaltstössel (5), die in den Löchern verschiebbar angeordnet sind, zwei Steuerorgane (7), die mit den Schaltstösseln in Wirkeingriff bringbar sind, Mittel (8) zur Betätigung der Steuerorgane und zwei Rückstellungselemente (9) für die Steuerorgane. Die Steuerorgane sind im Träger bezüglich der Antriebswelle radial in eine erste Stellung verschiebbar, um die Kupplungsvorrichtung in eine Antriebsstellung zu schalten und in eine zweite Stellung verschiebbar, um die Kupplungsvorrichtung in eine Freilaufstellung zu schalten Die Rückstellungsorgane (9) sind innerhalb der Antriebswelle (1) angeordnet, um die Steuerorgane (7) in die zweite Stellung zu verschieben. Mit dieser Anordnung wird die Rückstellung der Steuerorgane gewährleistet. Bei einer Kupplungsvorrichtung für eine Rotations-Schaftmaschine mit einer derartigen Vorrichtung sind zum Kuppeln der Antriebswelle mit der Exzenterscheibe zwei Mitnehmer vorgesehen, die gleichzeitig in und ausser Eingriff bringbar sind, um die auf die Mitnehmer einwirkende Haltekraft aufzuteilen. <IMAGE>
